LG's ultra-thin Gallery Series OLED TVs deserve an attractive sound bar to match, like the LG GX. This bar can be placed on a tabletop, but it looks especially slick mounted on the wall. If you don't have a Gallery TV, no worries, the GX can beautifully complement almost any modern flat panel.

The GX system is nice and compact but it doesn't skimp on sound. The sound bar has dedicated left, right, and center channels. Built-in Meridian Technology expands the soundfield, making it both wider and deeper. Both Dolby Atmos and DTS:X are also supported through the eARC (enhanced Audio Return Channel) HDMI connection.

The included powered subwoofer fills in the low end so you can feel the action onscreen. It's also wireless, allowing additional flexibility when placing the subwoofer. As long as the sub has gets AC power, you're good to go.

LG additionally offers optional SPK8-S wireless speakers, which expand your home theater system to 5.1 channels and provide true surround sound.

The GX's 4K video passthrough supports Dolby Vision™ and HDR10. That means you can connect your video source directly to the sound bar and send crisp, high-contrast Ultra HD video to your TV via HDMI. The GX also has a USB input that supports high-resolution audio, letting you listen to detailed 24-bit/192kHz music files.

Built-in Bluetooth lets you stream audio content from compatible computers, smartphones, tablets, and even some TVs. The GX also upsamples Bluetooth and other audio sources to enhance their sound quality.
